The standard audio circuits of video cassette recorders and the recording circuits of tape decks use AC bias recording to record the audio signal onto the tape. This bias voltage is some tens of volts, and a high-capacity bias-side switch is required to electronically switch the head when in playback or record mode. The BA7755A and BA7755AF are high-voltage switching ICs designed to switch voltages as high as 65VDC or AC120VP-P (f = 70Hz). |
